Product Overview
The Pentair IntelliFlo 2 Variable Speed Complete Power End Without Drive | PSD VSPOWEREND is a replacement power-end assembly designed for compatible Pentair IntelliFlo 2 VST / IntelliFlo VSF-style variable-speed pump systems.
This assembly is intended for situations where the pump’s wet-end housing and existing drive are still usable, but the motor-side power end or internal hydraulic components need replacement. It provides a practical repair option for restoring pump performance without replacing the complete pump.
This version is supplied without the variable-speed drive, making it ideal for installations where the existing drive/controller is being reused.
Ideal For
- Pentair IntelliFlo 2 VST pump repairs
- Compatible IntelliFlo VSF pump repairs
- Replacing worn or damaged motor-side assemblies
- Restoring pump flow and hydraulic performance
- Service jobs where the existing drive is still working
- Pool professionals rebuilding compatible Pentair pumps
- Avoiding full pump replacement when the wet end and drive are usable
- Repairing pumps with motor, seal plate, impeller, or diffuser-side damage
- Professional pool equipment pad service work
Key Features
- Complete replacement power end — designed to restore the motor-side operation of compatible IntelliFlo 2 pump systems.

- Compatible with IntelliFlo 2 VST-style systems — intended for select Pentair IntelliFlo 2 VST / IntelliFlo VSF pump applications.
- Helps restore pump performance — useful for worn, noisy, leaking, or damaged power-end assemblies.
- Includes core hydraulic components — commonly used to replace motor-side components such as the motor, seal plate, impeller, and diffuser assembly depending on supplier build.
- Cost-effective repair option — avoids replacing the full pump when compatible existing parts are still in good condition.
- Professional-grade repair assembly — intended for qualified pool technicians familiar with Pentair variable-speed pump systems.

Benefits
The PSD VSPOWEREND assembly is a practical repair solution for compatible Pentair IntelliFlo 2 variable-speed pumps. When the power end fails but the drive and pump housing are still functional, replacing only the power end can reduce repair cost and avoid unnecessary equipment replacement.
This assembly helps restore water movement, pressure, and circulation performance in compatible systems. It is especially useful for pool service professionals who need a complete motor-side replacement option instead of rebuilding the pump one part at a time.
Because the drive is not included, this product is best suited for systems where the existing drive has been tested and confirmed to be operational.

Compatibility Notes
This product is intended for compatible Pentair IntelliFlo 2 VST / IntelliFlo VSF-style pump systems. Before ordering, confirm the existing pump model, drive condition, motor compatibility, seal plate style, impeller configuration, and wet-end housing compatibility.
This assembly should not be ordered solely by appearance. Pentair IntelliFlo, IntelliFlo 2, IntelliFlo VSF, IntelliPro, and other variable-speed pump models may use different power ends, drives, housings, or internal components.
Installation Notes
This power end should be installed by a qualified pool professional or pump technician. Before installation, turn off all power at the breaker and confirm the pump cannot restart during service.
The existing drive should be tested before installation because this assembly does not include the drive. Inspect the pump housing, volute gasket, seal plate gasket, shaft seal, diffuser O-ring, drive hardware, bonding connection, and plumbing unions before reassembly.
After installation, verify proper drive mounting, electrical connections, priming, pump rotation, speed programming, leak-free operation, and system flow.
